How long did it take to build the roman temple of juptier?

Answer 1

Presumably you mean the Temple of Jupiter Optimus Maximus (there were many temples of Jupiter). It is not known precisely. It was commissioned by the fifth king of Rome, Tarquinius Priscus, who only built the foundations. The sixth king, Servius Tullius, did not take on this project. The temple was completed by the seventh king, Tarquinius Superbus, who reigned form 535 BC to 509 BC. The temple was finished in 509. However, the year this king resumed construction is not known.
